Abstract

A sensor device for speed measurement on a wheel of a vehicle includes a sensor carrier with an integrated sensor to sense the rotation of a pole wheel that rotates along with the wheel. The sensor device has a clamping mechanism integrated into the sensor carrier by which the sensor carrier can be displaceably clamped into a holding opening in the region of the wheel and/or in any orientation with respect to rotations about the longitudinal axis of the sensor carrier. The sensor arrangement can be mounted with less effort and more cost-efficiently than with the current international standard of combining a clamping bush and subsequently mounted rod sensor. Spring-loaded clamps can be fastened as terminal blocks in longitudinal grooves in the sensor, and the spring-loaded elements thereof can protrude over the circumference of the sensor prior to mounting.

Claims

1. A sensor device for speed measurement on a wheel of a vehicle, the sensor device comprising a sensor carrier;

a sensor integrated in the sensor carrier to sense the rotation of an exciter wheel co-rotating with the wheel; and

a clamping mechanism integrated in the sensor carrier, by which the sensor carrier is at least one of (i) displaceably clampable in a holding opening in a region of the wheel and (ii) clampable in any orientation in respect of rotations about a longitudinal axis of the sensor carrier.

2. The sensor device as claimed in claim 1, wherein parts of the clamping mechanism project partially radially beyond the housing of the sensor carrier when the sensor carrier is unclamped.

3. The sensor device as claimed in claim 1, wherein the clamping mechanism includes at least one clamping strip extending in an axial direction laterally relative to the sensor carrier and at least one spring element to effect a defined friction connection between the sensor carrier and the holding opening in an axial direction of the sensor carrier.

4. The sensor device as claimed in claim 3, wherein the at least one clamping strips is configured such that the at least one spring elements one of automatically counteracts a reversal of an axial displacement of the sensor carrier in the holding opening and supplements the axial displacement with an additional contribution when a frictional connection is established following the axial displacement.

5. The sensor device as claimed in claim 1, wherein the sensor carrier is configured to counteract abrasive behavior on the sensor carrier by the exciter wheel.

6. The sensor device as claimed in claim 1, wherein the sensor is an active sensor arranged on a sensor head of the sensor carrier for active detection of rotation of the exciter wheel.

7. The sensor device as claimed in claim 1, wherein the sensor is a passive sensor arranged on a sensor head of the sensor carrier for passively recording rotation of the exciter wheel.

8. A vehicle brake system, comprising a plurality of brakes for at least one of braking and fixing wheels of the vehicle;

a plurality of sensor devices for speed measurement on the wheels, at least one of the sensor devices being the sensor device as claimed in claim 1; and

an electronic brake system configured to at least one of control and regulate the brakes based at least in part on signals from the sensor devices, the electronic brake system being connected to the sensor devices by one of an electrical signal line and a data line.

9. A vehicle comprising the sensor device as claimed in claim 1.

10. A method for measuring speed on a wheel of a vehicle, comprising utilizing the sensor device as claimed in claim 1.

11. The sensor device according to claim 1, wherein the sensor carrier is a rod.

12. The sensor device according to claim 1, wherein the sensor carrier is axially displaceably clampable in the holding opening in the region of the wheel.

13. A vehicle, comprising a brake system, the brake system including a plurality of brakes for at least one of braking and fixing wheels of the vehicle, a plurality of sensor devices for speed measurement on the wheels, at least one of the sensor devices being the sensor device as claimed in claim 1, and an electronic brake system configured to at least one of control and regulate the brakes based at least in part on signals from the sensor devices, the electronic brake system being connected to the sensor devices by one of an electrical signal line and a data line.
